Question 25 is based on the passage you have just heard.

听力原文

        (22) [Campaigners have warned that the British government is not doing enough to prevent left-handed pupils from falling behind their peers.] They claim that thousands of children are still being penalized for being left-handed. This is due to a lack of action from ministers who failed to take any meaningful action for years. It is feared that a failure to address early year challenges such as poor handwriting, leads to much more serious problems down the line with these pupils facing reduced career prospects.

        (23) [Studies in recent years show that left-handed children are more likely to suffer with learning difficulties, and their scores are lower on IQ tests.] Campaigners feel it’s strange that children in British schools are penalized because they happen to be left-handed. They don’t understand why successive governments have failed to act on this. (24) [They want the Department of Education to record which children are left-handed and what their educational attainments are] since they make up some 10% of the population. In early year education, left-handed children are struggling and making a mess of their handwriting. Educators don’t know how to deal with this. In many cases, there’s no active help and a lack of teacher training.

        Campaigners point out that a high percentage of the prison population is left-handed. (25) [They say that these prison numbers are unusually high and ask why it is the case.]

25. What do the campaigners want to know about left-handed prisoners?

解析：B。录音结尾提到，活动人士指出囚犯中左撇子比例很大，数量异常高，并追问为什么会这样（why it is the case），其中the case指的就是前面的these prison numbers are unusually high。B项与此内容相符，其中的Why their numbers are so high对应录音中的why it is the case，故B项为正确答案。

错项排除：A项利用录音中的number进行干扰，但录音中并未出现与reduced相关的内容，故A项排除。录音中提到，活动人士指出监狱中左撇子比例很高（a high percentage），C项的What percentage与此相悖，故排除。录音中并无提到左撇子囚犯比重是降低还是增高，故D项错误。
